Answer 2

Answer:

We will get the value of $n=-\frac{2}{3} .$

Step-by-step explanation:

• We have to evaluate the above expression by using the given data.

        Given data:- $3n+7=5.$

        To find:- Value of n.

        Solution:-

• Here we will use the transposition method.

• Transposition is one of the linear equations.

• To solve the transposition method we will Identify the variables and constants.

• Then we Simplify the equation in LHS and RHS.

• Now Simplify the equation using arithmetic operations.

        $3n+7=5\\=>3n=5-7\\=>3n=-2\\=>n=-\frac{2}{3}$
